Of those invitees, Jonas is already here to DJ Saturday at Hyde Bellagio. Ja Rule only ever seems to be in Vegas, appearing frequently with other celebs. J-Lo’s on-off-on lover Casper Smart is expected, too, of course.

As for J-Lo’s Planet Hollywood production, she just signed up for another 21 performances of dancing to “On The Floor,” “Dance Again” and other hits at Planet Hollywood Resort. Tickets went on sale Friday for $60-$1,000 plus taxes and fees.

Lopez also announced a new TV talent show she’s producing, although host(s) and judges haven’t been named. It’s called “World of Dance” and will air on NBC, where she already stars in the police procedural “Shades of Blue.” Anyone seen it?

FREEBIES FOR ROAD TRIPPERS

Google is doling out free gas, a free burger and free iced coffee at iconic California stops between L.A. and Vegas Friday and Saturday.

As seen on Google Maps’ Twitter page, you can get a free iced coffee under the world’s largest thermometer in Baker, a free burger at Peggy Sue’s Diner in Yermo and 10 gallons of free gas at Cima Road Shell in Nipton.

Google Maps can give you voice and screen directions to all three places, but don’t leave Google Maps running on your screen the whole trip unless you need to.

A security software company this week said Google Maps is the second-biggest battery-draining app on Android phones, after the Facebook app.

So before you go anywhere, go to “Offline Area” in Google Maps, choose how big of a map you want to download on Wi-Fi, and that will help cut down on data usage and battery drain.

In typical Google fashion, details are scant, but the LA Times claims the freebies were getable till 8 p.m. Friday and from 11 a.m. to 7 p.m. Saturday.

THE FAMOUS STRANGER

Swedish actress Alicia Vikander may have won the Oscar for “The Danish Girl,” but she’s not super-recognizable.

On the “Today” show, she said a Vegas cabby looked right at her — this was months ago during the filming of the new “Bourne” movie — and told her, “You might just see Matt Damon on the street.”

Vikander, who also portrayed the central artificial intelligence character in “Ex Machina,” was here to act in “Jason Bourne.”

You can’t blame the cabby. Since she alters her appearance so much on camera, I wouldn’t know her if she gave me a dollar for bottled water on a pedestrian bridge.
